一般一个应用在一定时间内多次重复发送同一个应用请求被认为是loops on same request。这在Xwin协议中是正常的，不断请求鼠标的位置。
Loops on Same Request
The Expert generates the Loops on Same Request alarm when it sees the application process on one station send out the same request even though it has already received the appropriate reply from the destination station. Only requests that are sent within the time specified by the Filter time threshold are considered "repeated."
Possible causes:
This may be legitimate, depending upon the application. For example, some print servers check for print requests every few seconds, resulting in many repetitions of the same request. You can eliminate this situation by lowering the Filter time threshold.
Particular applications may be inefficient. For example, some X Windows applications continually check the location of the mouse cursor, which can cause network traffic of this type.
Excessive repeated requests are characteristic of applications that do not use the network efficiently, or that are not designed to be used over networks.
If the request is a Novell NDS verb request, it may indicate the need to partition the NDS tree among more servers. However, the verbs DSV_Resolve_Name, DSV_Read, and DSV_Get_Server_Address are often sent out as part of the NDS protocol |
